VITA 46, 48, and 65: The Next Generation VME system replacement. VITA 46 is the VPX base electrical and mechanical specification. VITA 48 is the VPX REDI cooling spec. VITA 65 is Open VPX. Open VPX was the industry's attempt to bring order to chaos. Open VPX methodically defines a system of profiles that would fully explain the interactions between the backplane and plug-in modules. The profiles are the physical mapping of resources in the system. This information can then be used to determine compatibility.

This paper presents the thermal analysis performed on an aircraft engine Electronic Control Unit (ECU) installed in the engine environment. Part of the nacelle and ECU are modeled with and without cooling air, as specified by the engine manufacturer. Different geometric configurations are simulated providing boundary conditions for a detailed thermal analysis of the ECU itself.

Using Computational Fluid Dynamics (CFD) is no longer relegated to the realm of the specialist. A new class of CFD analysis software is proving to be highly effective at performing heat transfer analysis, enabling mechanical engineers to accelerate key decisions at their workstations and without the need for CFD specialists. Embedded into the MCAD environment, this intuitive process allows designers to optimize a product during the design stages reducing manufacturing costs across a wide range of mechanical designs and systems.

The counterfeiting of semiconductor components is escalating at an unprecedented rate. With increasingly sophisticated methods, counterfeit components are produced in many areas of the world and distributed globally. Additionally, unauthorized distributors render genuine parts substandard through improper handling. To make matters worse, semiconductors are being altered through a practice known as "malicious insertion" to cause damage or failure to the parts in which they are installed, or to gather intelligence.

The Symmetricom(r) QUANTUM(tm) Chip Scale Atomic Clock (SA.45s CSAC) delivers the accuracy and stability of an atomic clock to portable applications for the first time. That means that when it comes to the next era in atomic timekeeping, the clock is already running.

The CeeLok FAS-T connector, a new high-speed circular I/O, combines the ruggedness of a MIL-C-38999-style design with an insert specifically configured for 10 Gbit-Ethernet transmission. Additionally, it is a small-form-factor connector system that is field repairable and supports data rate requirements for current and next-generation electronic systems in Aerospace and Defense applications.

This application note along with its corresponding white paper 1MA207 show how to use the Rohde and Schwarz radar product portfolio to tackle test and measurement tasks in modern radar technology. Target groups are students who want to become familiar with radar issues as well as radar professionals who want to solve certain test and measurement tasks.

After its initial implementation in civil mobile telephones, the concept of a software defined radio (SDR) has now started making inroads in radios used for military applications. This document provides an introduction to SDR as used for military radios and presents the relevant T and M solutions offered by Rohde and Schwarz.
